[. . . ] PD 38 laser range meter Contents It is essential that the operating instructions are read before the range meter is used the first time. Always keep these operating instructions together with the range meter. Ensure that the operating instructions are with the range meter when it is given to other persons.

These are single distance measurement and continuous distance measurement. The continuous measurement mode is used for setting out given distances or offsets and is also used where distance measurements are more difficult, e. g. Operation 7. 4. 4 Measuring from corners The spike is used when measuring diagonally across rooms or from inaccessible corners. This automatically sets the measuring reference to the end of the spike. The range meter takes the extended reference point into account and corrects the measured distances accordingly. 7. 4. 5 Measuring with the aid of target objects When taking measurements to outside corners, e. g. on buildings, perimeter fences, etc. , boards, bricks or other suitable objects can be used as the target. Use of the PDA 50 target plate is recommended for long distances and in unfavourable light conditions, e. g. Position the range meter with the spike at the desired starting point for the measurement and aim towards the target. 3. The measured distance appears in the display. 7. 4. 6 Measuring in bright conditions The PD 38 has a built-in optical target sight. When measuring to very bright surfaces, the laser spot is often not visible. Thanks to the laser spot superimposed in the optical sight, you can always clearly and reliably aim at the target. We recommend use of the PDA 50 target plate for long distances and bright light conditions. 19 7. Operation 7. 4. 7 Taking measurements to rough surfaces When measuring to rough surfaces, e. g. coarse render, stucco, etc, an average distance value is measured with the centre of laser spot weighted higher than the edges of the laser spot. 7. 4. 10 Taking measurements to transparent surfaces It is not possible to measure distances to transparent materials, e. g. This is because light penetrates these materials and therefore measuring errors may occur. Measuring errors may also occur if measurements are taken through glass or if obstructions are present within the line of the laser beam. 7. 4. 11 Measuring ranges 7. 4. 11. 1 Increased distances ­ Taking measurements in the dark, at dawn, dusk and to shaded targets or with the front of the range meter shaded, generally leads to an increase in the measuring range. ­ Taking measurements to the PDA 50 target plate also results in an increase in the measuring range. 7. 4. 11. 2 Reduced distances ­ Taking measurements in very bright ambient light, e. g.
